Kak tolong bantuin ngerjain ​

Jawab:

Penjelasan dengan langkah-langkah:

9.

sin 30⁰ = RS/PR

1/2 = RS/24

2RS = 24

RS = 24/2

RS = 12

cos 30⁰ = PS/PR

√3/2 = PS/24

2PS = 24√3

PS = 12√3

tg 45⁰ = RS/SQ

1 = 12/SQ

SQ = 12

PQ = PS + SQ

.     = 12√3 + 12

.     = 12 ( √3 + 1 ) cm

opsi pilihan ( b )

semoga bisa membantu
